FIELD OF THE INVENTION

This disclosure relates generally to social networking, and more specifically to performing social network functions in response to detected matrix codes.

SUMMARY

The present disclosure discloses systems and methods for performing social networking service functions utilizing matrix codes. A matrix code reader may detect a matrix code, which may be displayed along with an instance of content and include information identifying the instance of content. The matrix code reader may obtain user information associated with a social networking service and, based at least on the information identifying the instance of content and the user information, the matrix code reader may transmit an instruction to the social networking service to perform a social networking service function. The social networking function that the social networking service is instructed to perform may be any kind of function supported by the social networking service such as posting one or more status updates regarding the instance of content, posting one or more comments regarding the instance of content, scheduling one or more events associated with the instance of content, posting at least one review of the at least one instance of content, submitting a request to join a group associated with the at least one instance of content, and so on.

The matrix code reader may obtain the user information and/or the instruction to perform the social networking service function from information included in the matrix code, from a non-transitory storage medium of the matrix code reader, from a user, and so on. If the matrix code reader obtains the user information and/or the instruction to perform the social networking service function from information included in the matrix code or the non-transitory storage medium, the matrix code reader may determine that additional information is needed. In such cases, the processing unit may prompt a user for the additional information and receive such additional information in response to the prompt. Even in situations where the matrix code reader does not determine that additional information is required, the matrix code reader may prompt a user before transmitting the instruction to the social networking service in order to confirm that the user desires the instruction to be transmitted.

In one or more implementations, the social networking service may be an independent service provider entity such as Facebook™, MySpace™, Twitter™, and so on. In other implementations, the social networking service may be software and/or hardware tools that are not part of an independent service provider entity which users set up to function as social networking services such as calendaring programs, mass email or text message lists, and so on.

In some implementations, information indicating that and instruction to perform one or more social networking service functions may be included in the matrix code and the matrix code reader may determine to transmit the instruction based on such information. However, in other implementations, the matrix code may not include any user information and the matrix code reader may be configured to select an instruction to perform a social networking function related to a captured matrix code anytime a captured matrix code includes information identifying an instance of content. Such selection may be performed by consulting defaults or user preferences stored in a non-transitory storage medium of the matrix code reader, by prompting a user, and so on.

In various implementations, the instance of content may be provided to a display device by an electronic device such as a set top box, a digital video recorder, a television tuner, a content receiver, a digital video disk player, a movie theater projection system, a home computer, and so on. The instance of content that is provided may be stored in the non-transitory storage medium, received from a content source, and so on. In some instances, the instance of content may already include the matrix code when received by the electronic device. In other instances, however, the electronic device may generate the matrix code, modify the matrix code, add the matrix code to the instance of content, and so on. In implementations where the electronic device generates or modifies the matrix code, the electronic device may obtain the information identifying the content, the user information, information regarding the instruction to perform the social networking function, and so on and may include such information in the matrix code before adding the matrix code to the instance of content.

It is to be understood that both the foregoing general description and the following detailed description are for purposes of example and explanation and do not necessarily limit the present disclosure. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate subject matter of the disclosure. Together, the descriptions and the drawings serve to explain the principles of the disclosure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The description that follows includes sample systems, methods, and computer program products that embody various elements of the present disclosure. However, it should be understood that the described disclosure may be practiced in a variety of forms in addition to those described herein.

Social networking services, whether independent service provider entities (such as Facebook™, MySpace™, Twitter™, and so on) or tools that are not part of an independent service provider entity which users set up to function as social networking services (such as calendaring programs, mass email or text message lists, and so on), are increasingly becoming an integral part of how people interact with each other in the modern world. Users utilize such social networking services to maintain contact with other users, inform other users of their thoughts and events in their lives, inform themselves of the thoughts and life events of other users, and so on. Users even utilize social networking services to communicate with other users regarding their viewing of content (such as movies, television programs, and so on) which may not even be related to the social networking service which is utilized. They may communicate to others that they are viewing the content, indicate their thoughts regarding the content, determine who else has viewed the content, schedule events related to the content, and so on.

However, it may be inconvenient and burdensome for users to utilize social networking services to communicate with other social networking service users regarding their viewing of content while they are viewing such content. Frequently, users must enter information regarding the social networking service (such as information to access the social networking service, log in information, indications of which functions they wish to utilize, and so on) into a device (such as a computing device) other than the device they are utilizing to view the content (such as a television, a movie theater screen, and so on). The amount of information a user is required to enter in order to utilize the social networking service may discourage the user from utilizing the social networking service he otherwise desires to utilize. Further, such social networking service utilization may distract the user from the user's primary purpose of viewing the content.

The present disclosure discloses systems and methods for performing social networking service functions utilizing matrix codes. A user may utilize a matrix code reader device to detect one or more matrix codes. The matrix code may be displayed along with one or more instances of content that a user is viewing and include information identifying the instance of content. The matrix code reader device may obtain user information for the user that is associated with one or more social networking services. Then, based at least on the information identifying the instance of content and the user information, the matrix code reader device may transmit one or more instructions to the social networking service to perform one or more social networking service functions. Hence, users may be able to direct the performance of social networking service functions related to content they are viewing without having to enter as much information and without having to distract themselves from the content as much as they otherwise would have. Thus, it may be more convenient and less burdensome for users to utilize social networking service functions related to content that they are viewing.

FIG. 1 is a block diagram illustrating a system 100 for performing social networking service functions utilizing matrix codes. The system 100 includes one or more matrix code readers 101, one or more display devices 102, and one or more social networking service computing devices 104. The matrix code reader may be any kind of electronic device capable of detecting (or capturing) matrix codes (such as QR™ codes) such as a cellular phone, a smart phone, a tablet computer, a mobile computer, a personal digital assistant, and so on. The display device may be any kind of display device such as a movie theater screen, a television, a computer monitor, a cathode ray tube display, a liquid crystal display, and so on.

The display device 102 may display one or more instances of content. The instance of content may be content such as a television program, a movie, a commercial, an instructional video, and so on. The instance of content may also include one or more matrix codes (such as QR™ codes) which may include information identifying the instance of content (such as a title, program identifier, description, and so on).

The matrix code reader 101 may include one or more processing units 106, one or more non-transitory storage media 107 (which may take the form of, but is not limited to, a magnetic storage medium; optical storage medium; magneto-optical storage medium; read only memory; random access memory; erasable programmable memory; flash memory; and so on), one or more input/output components 108 (such as keyboards, mice, touch screens, touch pads, displays, virtual keyboards, microphones, and so on), one or more communication components 109, and one or more optical detectors 110 (such as still image cameras, video cameras, barcode readers, and so on). The processing unit may execute instructions stored in the non-transitory storage medium to detect the matrix code displayed by the display device 102. The processing unit may also execute instructions stored in the non-transitory storage medium to obtain user information associated with the social networking service associated with the social networking service computing device 104 and transmit one or more instructions to the social networking service computing device via the communication component 109 to perform one or more social network service functions based at least on the information identifying the instance of content and the user information.

The social networking function that the processing unit 106 instructs the social networking service computing device 104 to perform may be any kind of function supported by the social networking service associated with the social networking service computing device. For example, the function may include posting one or more status updates regarding the instance of content (such as a status update indicating that the user is currently watching the content), posting one or more comments regarding the instance of content (such as a comment asking whether other users are watching the instance of content), scheduling one or more events associated with the instance of content (such as scheduling a party for other users to attend after the instance of content finishes), posting at least one review of the at least one instance of content (such as an in-depth review of the instance content, an indicating that the user likes the instance of content, and so on), submitting a request to join a group associated with the at least one instance of content (such as a request to join a fan group for the instance of content, requesting to join an email list for updates related to the instance of content, and so on), and so on.

In some instances, the processing unit 106 may obtain the user information and/or the instruction to perform the social networking service function from information included in the matrix code. In other instances, the matrix code may not include the user information and/or the instruction to perform the social networking service function and the processing unit may obtain the user information and/or the instruction to perform the social networking service function from information stored in the non-transitory storage medium 107, such as information stored in one or more default settings files, information previously received from a user via the input/output component 108 and stored in one or more user preference files stored in the non-transitory storage medium, and so on. In still other instances, the processing unit may obtain the user information and/or the instruction to perform the social networking service function by prompting a user for such information and receiving such information from a user via the input/output component.

In various instances where the processing unit 106 obtains the user information and/or the instruction to perform the social networking service function from information included in the matrix code or the non-transitory storage medium 107, the processing unit may determine that additional information is needed in order to transmit the instruction to the social networking service computing device 104. In such cases, the processing unit may prompt a user for the additional information and receive such additional information in response to the prompt via the input/output component 108. For example, the user information may specify a network address for the social networking service computing device and to post a comment regarding the instance of content, but may not include the comment itself. As such, the processing unit may prompt a user for a comment regarding the instance of content and may transmit an instruction to post the comment after the comment is received from the prompted user.

Even in situations where the processing unit 106 obtains the user information and/or the instruction to perform the social networking service function from information included in the matrix code or the non-transitory storage medium 107 and does not determine that additional information is required, the processing unit may prompt a user via the input/output components 108 before transmitting the instruction to the social networking service computing device 104. For example, the user information may specify a network address for the social networking service computing device and to post a status update that a user is watching the instance of content, but the processing unit may prompt the user to confirm that he wishes the status update to be posted. The processing unit may then transmit the instruction to post the status update when the confirmation is received from the prompted user.

In some implementations, information indicating that and instruction to perform one or more social networking service functions may be included in the matrix code and the matrix code reader 101 may determine to transmit the instruction based on such information. However, in other implementations, the matrix code may not include any user information and the matrix code reader may be configured to select an instruction to perform a social networking function related to a captured matrix code anytime a captured matrix code includes information identifying an instance of content. Such selection may be performed by consulting defaults or user preferences stored in the non-transitory storage medium 107, by prompting a user via the input/output components 108, and so on.

FIG. 2 illustrates a method 200 for performing social networking service functions utilizing matrix codes. The method 200 may be performed by the electronic device 101 of FIG. 1. The flow begins at block 201 and proceeds to block 202 where the matrix code reader 101 operates. The flow then proceeds to block 203 where the processing unit 106 determines whether or not the optical detector 110 detects a matrix code that includes information specifying the content with which the matrix code is included. If so, the flow proceeds to block 204. Otherwise, the flow returns to block 202 where the matrix code reader continues to operate.

At block 204, after the optical detector 110 detects a matrix code that includes information specifying the content with which the matrix code is included, the processing unit 106 decodes the matrix code. The flow then proceeds to block 205 where the processing unit determines whether or not the matrix code includes user information related to a social networking service. If not, the flow proceeds to block 207. Otherwise, the flow proceeds to block 206.

At block 206, after the processing unit 106 determines that user information related to the social networking service is included in the matrix code, the processing unit transmits an instruction to perform a social network function based on the information specifying the instance of content and the user information to the social networking service computing device 104 that is associated with the social networking service. The flow then returns to block 202 where the matrix code reader 101 continues to operate.

At block 207, after the processing unit 106 determines that user information related to the social networking service is not included in the matrix code, the processing unit determines whether the user information is stored in the non-transitory storage medium 107 of the matrix code reader 101. If so, the flow proceeds to block 208 where the processing unit retrieves the information before the flow proceeds to block 206. Otherwise, the flow proceeds to block 209.

At block 209, after the processing unit 106 determines the user information is not stored in the non-transitory storage medium 107 of the matrix code reader 101, the processing unit prompts a user for the user information via the input/output components 108 and the flow proceeds to block 210. At block 210, the processing unit receives the user information from the prompted user via the input/output components and then the flow proceeds to block 206.

Although the method 200 illustrates and describes the matrix code reader 101 decoding the matrix code and transmitting the instruction directly to the social networking service computing device 104, other contemplated arrangements are possible without departing from the scope of the present disclosure. Returning to FIG. 1, in some implementations, the system 100 may include a matrix code computing device 115 which the matrix code reader 101 may interact with via the communication component 109 to decode the matrix code, transmit instructions to the social networking service computing device 104, and so on.

In various implementations, the instance of content may be provided to the display device 102 by an electronic device 103. The electronic device may be any electronic device such as a set top box, a digital video recorder, a television tuner, a content receiver, a digital video disk player, a movie theater projection system, a home computer, and so on. The electronic device may include one or more processing units 111 which execute instructions stored in one or more non-transitory storage media 112 to provide the instance of content to the display device via the output component 113. The instance of content that is provided may be stored in the non-transitory storage medium, received from a content source 105 (such as a cable or satellite television provider, a video on demand provider, a digital video disk physical distribution network, and so on), and so on.

In some instances, the instance of content may already include the matrix code when received by the electronic device 103. In other instances, however, the electronic device may generate the matrix code, modify the matrix code, add the matrix code to the instance of content, and so on. In implementations where the electronic device generates or modifies the matrix code, the electronic device may obtain the information identifying the content, the user information, information regarding the instruction to perform the social networking function, and so on (such as from the non-transitory storage medium, via the communication component 114, from a user, and so on) and may include such information in the matrix code before adding the matrix code to the instance of content.

While the social networking computing device 104 and the associated social networking service is illustrated and described above as an independent service provider entity such as Facebook™, MySpace™, Twitter™, and so on, other contemplated arrangements are possible without departing from the scope of the present disclosure. In various implementations, the described social networking service may include software and/or hardware tools that are not part of an independent service provider entity which users set up to function as social networking services. Such tools may include as calendaring programs, mass email or text message lists, and so on. As such, in those implementations the social networking service computing device 104 may be a computing device that is configured to support the software and/or hardware tools which the user configures to function as social networking services.

FIGS. 3A-3D illustrate a user 302A-302D utilizing a system to perform social networking functions by capturing matrix codes 308B-308D displayed on a television 304A-304D. The system may be the system 100 of FIG. 1. As illustrated in FIG. 3A, the user 302A is watching Movie XYZ which is displayed on a television screen 305A of the television 304A. Also as illustrated, the user 302A has a smart phone 301A and a desktop computer 306A which is displaying a social networking service web site on a monitor screen 307A.

In FIG. 3B, the television 304B displays a matrix code 308B along with Movie XYZ on the television screen 305B. The matrix code 308B includes information specifying that the content displayed on the television screen 305B is Movie XYZ. Additionally, the matrix code 308B includes user information that specifies a network address for the social networking service web site displayed on the monitor screen 307B, log in information associated with the social networking service web site displayed on the monitor screen 307B for the user 302B, and an indication to post a status update on the social networking service web site displayed on the monitor screen 307B that the user 302B is watching Movie XYZ.

When, as depicted in FIG. 3C, the user 302C captures the matrix code 308C with the smart phone 301C, the smart phone 303C decodes the matrix code 308C to obtain the information included in the matrix code 308C. The smart phone 303C then displays a prompt on a smart phone screen 303C asking the user 302C whether or not to post an update to the social networking service web site displayed on the monitor screen 307C that the user 302C is watching Movie XYZ.

In some instances, the user 302C may not wish to share the fact that he is watching Movie XYZ with other users of the social networking service web site displayed on the monitor screen 307C. For example, Movie XYZ may constitute adult entertainment and the user 302C may not wish to alert other social networking service users that he watches adult entertainment and may respond negatively to the prompt displayed on the smart phone screen 303C utilizing input elements of the smart phone 301C.

However, as illustrated in FIG. 3D, if the user 302D responds affirmatively to the displayed prompt, the smart phone 301D transmits an instruction to the social networking service web site displayed on the monitor screen 307D to post a status update that the user 302D is watching Movie XYZ. Additionally, the smart phone 301D displays a message on the smart phone screen 303D indicating that the status of the user 302D has been updated on the social networking service web site displayed on the monitor screen 307D to indicate that the user 302D is watching Movie XYZ.

Although FIGS. 3A-3D illustrate and describe that the information utilized to transmit the instruction to post the status update to the social networking service web site is obtained by the smart phone 301A-301D from the matrix code 308B-308D, it is understood that other contemplated arrangements are possible. One of more portions of such information may be obtained from a non-transitory storage medium (not shown) of the smart phone 301A-301D, from the user 302A-302D, and so on. Further, although FIGS. 3A-3D illustrate and describe that the smart phone 301A-301D decode the matrix code 308B-308D and transmit the instruction to update the status of the user 302A-302D to the social networking service web site displayed on the monitor screen 307D, it is understood that other contemplated arrangements are possible. The smart phone 301A-301D may transmit the captured matrix code 308B-308D to one or more backend servers which may decode the matrix code. The smart phone 301A-301D may also communicate with the backend servers to transmit the instruction to update the status of the user 302A-302D to the social networking service web site displayed on the monitor screen 307D.

In the present disclosure, the methods disclosed may be implemented as sets of instructions or software readable by a device. Further, it is understood that the specific order or hierarchy of steps in the methods disclosed are examples of sample approaches. In other embodiments, the specific order or hierarchy of steps in the method can be rearranged while remaining within the disclosed subject matter. The accompanying method claims present elements of the various steps in a sample order, and are not necessarily meant to be limited to the specific order or hierarchy presented.

The described disclosure may be provided as a computer program product, or software, that may include a non-transitory machine-readable medium having stored thereon instructions, which may be used to program a computer system (or other electronic devices) to perform a process according to the present disclosure. A non-transitory machine-readable medium includes any mechanism for storing information in a form (e.g., software, processing application) readable by a machine (e.g., a computer). The non-transitory machine-readable medium may take the form of, but is not limited to, a magnetic storage medium (e.g., floppy diskette, video cassette, and so on); optical storage medium (e.g., CD-ROM); magneto-optical storage medium; read only memory (ROM); random access memory (RAM); erasable programmable memory (e.g., EPROM and EEPROM); flash memory; and so on.

It is believed that the present disclosure and many of its attendant advantages will be understood by the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the components without departing from the disclosed subject matter or without sacrificing all of its material advantages. The form described is merely explanatory, and it is the intention of the following claims to encompass and include such changes.
